Abstract

Background: Increased of high protein and β-carotene food consumption is expected may prevent PEM and VAD. Tempeh is a high-protein food stuff, while orange-fleshed sweet potato had high β-carotene content. Sweet bread with substitution of tempeh and orange-fleshed sweet potato flours is expected could be an alternative food which had high protein and β-carotene content.

Objective: Analyze the effect of tempeh and orange-fleshed sweet potato flour substitution on protein and β-carotene content, and organoleptic quality of sweet bread.

Method: An one factor completely randomized experimental study used 5 level of tempeh and orange-fleshed sweet potato flour substitution, which were 0%:0%, 0%:25%, 10%:15%, 15%:10%, and 25%:0%. Statistical analysis of protein and β-carotene content used One Way ANOVA followed by Tukey and Duncan test, while analysis of organoleptic quality used Friedman and Wilcoxon test.
